Recombinant interferon-beta (IFN-beta) protein is used successfully for the treatment of multiple sclerosis (MS). Gene therapy might be an alternative approach to overcome drawbacks occurring with IFN-beta protein therapy. A critical issue in developing a new approach is detection of biologically active IFN-beta in preclinical models. The goal of the(More)
Previous studies have shown that fibroblast growth factor (FGF)-1, FGF-2, and FGF-5 induce therapeutic angiogenesis. Here, we investigated the potential of FGF-4 for therapeutic neovascularization in comparison to vascular endothelial growth factor (VEGF), using adenoviral gene transfer in a novel rabbit hind limb ischemia model, with ischemia restricted to(More)
rDSPA alpha 1 (recombinant Desmodus salivary plasminogen activator alpha 1) is a recombinant protein corresponding to a natural plasminogen activator from the vampire bat Desmodus rotundus. The thrombolytic properties of rDSPA alpha 1 and tissue-type plasminogen activator (t-PA) were compared in a rat model of pulmonary embolism. Whole blood clots, produced(More)
Recombinant proteins are useful tools in biological research, drug development, and drug screening. Specially designed expression vectors have been developed to introduce cDNA for recombinant protein expression in mammalian cells. We have combined a dicistronic mRNA design for expression of the recombinant protein, using glutamine synthetase (GS) for(More)
This study illustrates the application of asymmetrical flow field-flow fractionation (AF4) and light scattering analysis during the development of a gene delivery vehicle based on virus-like particles (VLPs) derived from the human polyoma JC virus. The analytical system was created by connecting an AF4 apparatus to the following detectors: diode array,(More)
Recombinant retroviral vectors are useful tools for gene transfer in both gene therapy and research applications. An enhanced form of green fluorescent protein has been incorporated into recombinant retroviruses as a marker to follow infected cells. In this paper, we extended the use of the fluorescent reporter to quantify protein expression using such(More)
Gene delivery of angiogenic growth factors is a promising approach for the treatment of ischemic cardiovascular diseases. However, success of this new therapeutic principle is hindered by the lack of critical understanding as to how disease pathology affects the efficiency of gene delivery and/or the downstream signaling pathways of angiogenesis. Critical(More)
Salivary plasminogen activator from the vampire bat Desmodus rotundus (DSPA alpha 1) is a promising new thrombolytic agent. Continuous growth of a stably transfected, methotrexate amplified, dhfr- CHO cell line yields up to 60 mg l-1 of DSPA alpha 1. Utilizing an engineered baculovirus 10 mg l-1 were produced in batches of Sf9 insect cells. Recombinant DSPA(More)
Experimental allergic encephalomyelitis (EAE) is a model of central nervous system (CNS) inflammation that follows immunization with certain CNS antigens. The course and clinical manifestations of EAE are similar to those of multiple sclerosis (MS) in humans; therefore, EAE has become an accepted animal model to study MS. The purpose of this study was to(More)
